Move on from my Bryston BDA-1?

I should add the main system is modest  As said Bluesound Node 2i streaming to the Bryston DAC wvia a Cardas Lightning coax cable then Kimber Kable Hero RCA interconnects to an NADC165BEE preamp with Wireworld Oasis 5 RCAs feeding a vintage Adcom GFA 5500 amplifier ending with DH Labs Q10 Silver Sonic bi-wire speaker cables to a pair of Totem Forest speakers. Thanks for your comments.

Thanks for the responses. All seem to agree the Bryston was advanced for its day and remains a solid performer, at least insofar as the basic internals are involved. Mesch asks "what kind of 'noticeable' difference are you looking for" and that is the fundamental issue that prompted my question. Honestly I can't answer that because I don't know what is out there given the tremendous advancement in delta sigma and R-2R DACS. My assumption is that the Bryston, while indeed capable (and currently providing what I judge to be a better option that the DAC in the Bluesound Node 2i) given its age must have been surpassed sonically by currently available DACs even in a lesser price range. To my ear the Topping D90 added much to the performance of my other system (principally used for home theater) where when listening to music feeds a Denon receiver to a pair of  B&W 805s speakers. While not all vintage equipment has been surpassed in performance by later technology, I guess I just believe I must be missing something with the Bryston. Unable to audition among highly regarded DACs such as the Cord Qutest, RME ADI 2, Denafrips Pontus II (ore even Ares II) and others I looked to the forum for suggestions and guidance.  

Interesting comment about the R-2R style docs. For the cost I am  interested in the Ares II which seems to be well reviewed. Regarding the comments regarding tube or tube-like sonic quality, when reviewed against other similarly priced DACs the Ares seems to be the most 'full blossomed", i.e. less analytical.

Would love to have the BDA-3 but $3,800 is well out of my budget.

While we are on the subject (and thanks for all of the input) what about the new Liberty II DAC that retails for just under $1K? I realize no one has had any chance to use or review this yet but if you have had experience with the original Liberty it would be valuable to see how it stacked up against those we already have been discussing. 

Just a thank you to those who responded. Sold the Bryston and purchased an Ares II. I expected a long wait for shipment but it arrived within 8 days of ordering and with several messages along the way confirming the order, tracking shipment, and thanking me for the purchase.
